Fine Grinding - A Refresher

Fine grinding is often conducted to regrind a rougher flotation concentrate prior to cleaning. As the concentrate is not the same composition as the ore ground in earlier comminution stages, it must be considered in isolation from the primary and secondary grinding circuits.

The Significance of Fine Grinding - Biodynamic Association

grinding is superior to fine grinding, but that a good horn silica preparation can be made even without any grinding—either by using the circa millimeter-sized quartz crystals embedded in the clay mineral rectorite, or by using any fine-grained beach or river sand. This recent article is very similar to a

Grinding of Metals: Origin and Cutting Action Industries ...

The small and hot chips produced in grinding operation have tendency to weld to wheel or workpiece. Further a large number of grains may have a large negative rake angle due to random grit orientation, and these instead of cutting, may rub. These factors make grinding process to be inefficient and consume high specific energy.

Fine grinding in a horizontal ball mill - ScienceDirect

01-04-2007  To aid in the economic liberation of fine-grained minerals, fine grinding was identified in the early 1990s as a suitable process for the minerals industry. Liberation options include a coarse primary grind and produce a concentrate and middling with re-grinding of the concentrate and/or the middling to finer sizes to achieve final liberation or fine grinding of the whole ore.

Energy Use of Fine Grinding in Mineral Processing ...

18-12-2013  As fine grinding is typically used on regrind applications, the feed tonnages to fine grinding circuits are small compared to head tonnages, typically 10 to 30 tph. However, the specific energies are often much larger than those encountered in intermediate milling and can be as high as 60 kWh/t.
